Description

[Technical field]

[0001] The present embodiment relates to a refrigerator. [Background technology]

[0002] For example, as disclosed in Patent Document 1, a refrigerator is considered that is configured to be able to determine the open / closed state of a storage compartment door that opens and closes the opening of the storage compartment. This type of refrigerator is equipped with a sensor that detects a magnet around the opening of the storage compartment, and also with a magnet on a handle of the storage compartment door. The sensor detects the magnet that approaches or moves away as the storage compartment door is opened or closed, and the open / closed state of the storage compartment door is determined based on the detection result. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-53606 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the refrigerator configured as described above, the magnet is configured to be located as close as possible to the sensor when the storage compartment door is in a closed state where the opening of the storage compartment is closed, thereby improving the accuracy of detection of the magnet by the sensor and, in turn, improving the accuracy of detection of the open / closed state of the storage compartment door. Therefore, it is preferable that the magnet housing part that houses the magnet is provided so as to protrude toward the sensor. However, if the magnet housing part is provided so as to protrude toward the sensor, the magnet housing part becomes conspicuous, which causes a problem of impairing the appearance.

[0005] Therefore, the present embodiment provides a refrigerator in which a magnet housing section for housing a magnet is provided so as to be oriented toward the magnet detection section, while the magnet housing section can be made less noticeable. [Means for solving the problem]

[0006] The refrigerator according to the present embodiment includes a storage compartment, a magnet detection unit provided around an opening of the storage compartment, a storage compartment door for opening and closing the opening of the storage compartment, and a magnet accommodating unit provided on the storage compartment door for accommodating a magnet to be detected by the magnet detection unit. The magnet accommodating unit is oriented toward the magnet detection unit and includes an extension unit extending in a direction intersecting the oriented direction. The magnet accommodating unit and the extension unit protrude toward the storage compartment beyond a portion directly below the magnet accommodating unit and the extension unit. The extension portion is provided on the left-right direction center side of a support portion that rotatably supports another storage compartment door located above the storage compartment door. .

[0008] Hereinafter, an embodiment of a refrigerator will be described with reference to the drawings. A refrigerator 10 shown in Fig. 1 has a rectangular insulated box 11 that forms the outer shell of the refrigerator, and has multiple storage compartments for storing food items inside. The insulated box 11 is an example of a refrigerator body that forms the main body of the refrigerator 10, and is configured with an insulating material such as a vacuum insulation panel or urethane foam between an inner box and an outer box.

[0009] Insulated box 11 is provided with refrigerator compartment 12 and vegetable compartment 13, which are maintained in a refrigeration temperature range, as various storage compartments for accommodating stored items such as food. Insulated box 11 is also provided with freezer compartment 14, small freezer compartment 15, and ice-making compartment 16, which are maintained in a freezing temperature range. In this case, vegetable compartment 13 is provided below refrigerator compartment 12. Small freezer compartment 15 and ice-making compartment 16 are arranged side by side in the left-right direction below vegetable compartment 13. Freezer compartment 14 is provided below small freezer compartment 15 and ice-making compartment 16.

[0010] The refrigeration compartment 12 has an opening 12a on its front surface. In this case, the opening 12a of the refrigeration compartment 12 is opened and closed by a single pivotable refrigeration compartment door 12D that pivots along the lateral direction of the refrigerator 10.

[0011] The vegetable compartment 13 has an opening 13a on its front side. In this case, the opening 13a of the vegetable compartment 13 is opened and closed by a single drawer-type vegetable compartment door 13D that slides along the front-rear direction of the refrigerator 10.

[0012] The freezer compartment 14 has an opening 14a on its front side. In this case, the opening 14a of the freezer compartment 14 is opened and closed by a single drawer-type freezer compartment door 14D that slides along the front-rear direction of the refrigerator 10.

[0013] The small freezer compartment 15 has an opening 15a on its front side. In this case, the opening 15a of the small freezer compartment 15 is opened and closed by a single drawer-type small freezer compartment door 15D that slides along the front-rear direction of the refrigerator 10.

[0014] Ice making compartment 16 has an opening 16a on its front side. In this case, opening 16a of ice making compartment 16 is opened and closed by a single pull-out small freezer door 16D that slides along the front-rear direction of refrigerator 10.

[0015] As shown in Figs. 2 and 3, the refrigerator compartment door 12D is configured to have a rotational system of either a so-called "left-opening type" or a "right-opening type".

[0016] 2 shows a configuration example in which the rotation method of refrigerator compartment door 12D is set to "left-opening type." In this case, the left end of refrigerator compartment door 12D as viewed from the front of refrigerator 10 is supported rotatably by rotation support part 12S in a closed state in which opening 12a of refrigerator compartment 12 is closed. Therefore, the left side of refrigerator compartment door 12D in the closed state in which opening 12a of refrigerator compartment 12 is closed becomes the rotation base end side, and the right side becomes the rotation free end side.

[0017] 3 shows a configuration example in which the rotation method of refrigerator compartment door 12D is "right-opening type." In this case, when refrigerator compartment door 12D is in a closed state in which opening 12a of refrigerator compartment 12 is closed, the right end portion of refrigerator compartment door 12D is rotatably supported by rotation support portion 12S when viewed from the front of refrigerator 10. Therefore, when refrigerator compartment door 12D is in a closed state in which opening 12a of refrigerator compartment 12 is closed, the right side becomes the rotation base end side, and the left side becomes the rotation free end side.

[0018] The refrigerator 10 also includes a magnet detector 20. The magnet detector 20 includes, for example, a well-known Hall IC sensor capable of detecting the magnetic force generated by a magnet. The magnet detector 20 is provided around the opening of the storage compartment, and in this case, is provided at the front end of a partition wall 21 that separates the refrigerator compartment 12 and the vegetable compartment 13.

[0019] As shown in Fig. 2, when the refrigerator door 12D rotates in a "left-opening" manner, the magnet detector 20 is provided on the left side of the center in the left-right direction of the front end of the partition wall 21, that is, on the rotation support part 12S side. As shown in Fig. 3, when the refrigerator door 12D rotates in a "right-opening" manner, the magnet detector 20 is provided on the right side of the center in the left-right direction of the front end of the partition wall 21, that is, on the rotation support part 12S side.

[0020] 4 and 5, refrigerator 10 is configured so that distance L between magnet detection unit 20 and rotation shaft 12R of rotation support unit 12S is the same whether the rotation type of refrigerator compartment door 12D is a "left-opening type" or a "right-opening type." Note that refrigerator 10 may be configured so that distance L between magnet detection unit 20 and rotation shaft 12R of rotation support unit 12S is different depending on whether the rotation type of refrigerator compartment door 12D is a "left-opening type" or a "right-opening type."

[0021] 2 to 5, the upper end of the vegetable compartment door 13D is provided with a handle 30. The handle 30 is a component on which the user's fingers are placed when opening and closing the vegetable compartment door 13D, and in this case, is provided so as to cover the entire upper end of the vegetable compartment door 13D.

[0022] 6, a plurality of magnet storage sections 31, in this case two, are provided at the rear of the handle section 30. One of the two magnet storage sections 31 is provided to the left of the center in the left-right direction of the handle section 30, and the other is provided to the right of the center in the left-right direction of the handle section 30. Furthermore, both of the two magnet storage sections 31 are formed as substantially rectangular storage sections oriented toward the partition wall 21 side, i.e., the magnet detection section 20 side.

[0023] Further, extending portions 32 are provided on the sides of the magnet accommodating portions 31. The extending portions 32 extend in a direction intersecting the orientation direction of the magnet accommodating portions 31, in this case, along the left-right direction of the refrigerator 10. Further, the rear end surface of the extending portion 32, i.e., the surface on the magnet detection portion 20 side, is flush with the rear end surface of the magnet accommodating portion 31, i.e., the surface on the magnet detection portion 20 side.

[0024] In this embodiment, the extension portion 32 includes an intermediate extension portion 32A and an outer extension portion 32B. The intermediate extension portion 32A is provided between the two magnet storage portions 31. The intermediate extension portion 32A is provided so as to connect the two magnet storage portions 31. On the other hand, the outer extension portion 32B is provided on the outside of the two magnet storage portions 31, that is, on the opposite side to the intermediate extension portion 32A. The outer extension portion 32B is provided in a non-facing portion that does not face the rotation support portion 12S in a closed state in which the vegetable compartment door 13D closes the opening 13a of the vegetable compartment 13.

[0025] Further, on the rear side of the handle portion 30, a step portion 33 recessed forward is formed outside the outer extension portion 32B. The rotation support portion 12S is accommodated in the step portion 33 when the vegetable compartment door 13D is in a closed state in which the opening 13a of the vegetable compartment 13 is closed.

[0026] At the rear side of the handle 30, a continuous, flush flat surface is formed consisting of the rear end surface of the magnet accommodating portion 31 and the rear end surface of the extension portion 32. It is preferable that the rear end surface of the extension portion 32 is completely flush with the rear end surface of the magnet accommodating portion 31, but it may be shifted slightly forward or rearward from the rear end surface of the magnet accommodating portion 31, for example, by about several mm.

[0027] 6, a slit 34 is provided on the rear end surface of the magnet accommodating portion 31. The slit 34 is an example of a communication portion, and penetrates the rear end surface of the magnet accommodating portion 31 to communicate the inside and outside of the magnet accommodating portion 31. In this case, the slit 34 is formed so as to extend in the up-down direction at the center in the left-right direction of the rear end surface of the magnet accommodating portion 31. The slit 34 is also formed so as to extend upward from the lower end of the rear end surface of the magnet accommodating portion 31. The slit 34 is a tapered slit that becomes narrower from the lower end toward the upper end.

[0028] 7 and 8, a magnet 40 is housed in the magnet housing portion 31. In this case, the magnet 40 is formed in a rectangular shape. A locking rib 41 that locks with the front end of the magnet 40 housed in the magnet housing portion 31 is provided in the front part of the magnet housing portion 31. In this embodiment, a plurality of locking ribs 41, in this case two locking ribs 41, are provided for one magnet housing portion 31.

[0029] 7 shows a configuration example of handle part 30 when refrigerator compartment door 12D is set to a "left-opening" rotation type. In this case, magnet 40 is accommodated in magnet accommodating part 31 on the left side when viewed from the front side of refrigerator 10. Magnet 40 accommodated in magnet accommodating part 31 on the left side when viewed from the front side of refrigerator 10 can be seen from the outside through slit 34.

[0030] On the other hand, magnet 40 is not accommodated in magnet accommodating portion 31 on the right side as viewed from the front side of refrigerator 10. In this case, wall portion 42 is provided in magnet accommodating portion 31 on the right side as viewed from the front side of refrigerator 10. Thus, wall portion 42 prevents magnet 40 from being accommodated in magnet accommodating portion 31 on the right side as viewed from the front side of refrigerator 10.

[0031] 8 shows a configuration example of handle portion 30 when refrigerator compartment door 12D is set to a "right-opening" rotation type. In this case, magnet 40 is accommodated in magnet accommodating portion 31 on the right side as viewed from the front side of refrigerator 10. Magnet 40 accommodated in magnet accommodating portion 31 on the right side as viewed from the front side of refrigerator 10 can be seen from the outside through slit 34.

[0032] On the other hand, magnet 40 is not accommodated in magnet accommodating portion 31 on the left side as viewed from the front side of refrigerator 10. In this case, wall portion 42 is provided in magnet accommodating portion 31 on the left side as viewed from the front side of refrigerator 10. Thus, wall portion 42 prevents magnet 40 from being accommodated in magnet accommodating portion 31 on the left side as viewed from the front side of refrigerator 10.

[0033] As illustrated in Figures 4 and 5, the refrigerator 10 also has a magnet housing section 12Dm, in which a magnet (not shown) is housed, at the bottom end of the refrigerator compartment door 12D. Regardless of whether the refrigerator compartment door 12D rotates in a "left-opening" or "right-opening" manner, the magnet housing section 12Dm is provided at a position facing the magnet detection section 20 when the refrigerator compartment door 12D is in a closed state in which the opening 12a of the refrigerator compartment 12 is closed. In other words, the magnet detection section 20 is configured to include a sensor for detecting the magnet 40 included in the vegetable compartment door 13D, and a sensor for detecting a magnet (not shown) included in the refrigerator compartment door 12D.

[0034] Furthermore, in a closed state in which the refrigerator compartment door 12D closes the opening 12a of the refrigerator compartment 12, the magnet accommodating section 12Dm is provided at a position that avoids being directly above the magnet accommodating section 31 that accommodates the magnet 40 of the vegetable compartment door 13D. More specifically, when the rotation method of the refrigerator compartment door 12D is a "left-opening type", the magnet accommodating section 12Dm of the refrigerator compartment door 12D is provided at a position to the right of the magnet accommodating section 31 that accommodates the magnet 40 of the vegetable compartment door 13D. On the other hand, when the rotation method of the refrigerator compartment door 12D is a "right-opening type", the magnet accommodating section 12Dm of the refrigerator compartment door 12D is provided at a position to the left of the magnet accommodating section 31 that accommodates the magnet 40 of the vegetable compartment door 13D.

[0035] In the refrigerator 10 according to the present embodiment exemplified above, the magnet accommodating section 31 is oriented toward the magnet detection section 20 and includes the extending section 32 extending in a direction intersecting the oriented direction. With this configuration, the magnet accommodating section 31 that accommodates the magnet 40 is oriented toward the magnet detection section 20, while the magnet accommodating section 31 can be made less noticeable by the extending section 32.

[0036] Therefore, in a closed state where the vegetable compartment door 13D closes the opening 13a of the vegetable compartment 13, the magnet 40 can be located as close as possible to the magnet detection unit 20 side, particularly in the front-to-rear direction, thereby improving the detection accuracy of the magnet 40 by the magnet detection unit 20, and thus improving the detection accuracy of the open / closed state of the vegetable compartment door 13D. Also, even if the magnet accommodating unit 31 is oriented toward the magnet detection unit 20 side in order to improve the detection accuracy of the magnet 40 in this way, the magnet accommodating unit 31 can be made less noticeable by the extension 32, and it is possible to avoid impairing the appearance.

[0037] Moreover, according to refrigerator 10, the rear end surface of magnet accommodating section 31 is configured to be flush with the rear end surface of extension section 32. With this configuration, magnet accommodating section 31 oriented toward magnet detection section 20 can be made even less noticeable by being buried in extension section 32.

[0038] Furthermore, in refrigerator 10, extension portion 32 is provided at a non-facing portion that does not face pivot support portion 12S. With this configuration, in a closed state in which vegetable compartment door 13D closes opening 13a of vegetable compartment 13, it is possible to prevent extension portion 32 from interfering with pivot support portion 12S. Therefore, opening 13a of vegetable compartment 13 can be well closed by vegetable compartment door 13D.

[0039] Moreover, refrigerator 10 is provided with a plurality of, in this case, two, magnet storage units 31. One magnet storage unit 31 is provided to the left of the center in the left-right direction when viewed from the front side of refrigerator 10, and the other magnet storage unit 31 is provided to the right of the center in the left-right direction when viewed from the front side of refrigerator 10.

[0040] According to this configuration, when the rotation method of the refrigerator compartment door 12D is set to the "left-opening type," that is, when the magnet detection unit 20 is provided on the front end of the partition wall 21 to the left of the center in the left-right direction, the magnet 40 can be accommodated in the magnet accommodating unit 31 on the left side when viewed from the front side of the refrigerator 10, and the magnet 40 can be detected well by the magnet detection unit 20.

[0041] Furthermore, when the rotation method of the refrigerator compartment door 12D is set to the "right-opening type," that is, when the magnet detection unit 20 is provided on the front end of the partition wall 21 to the right of the center in the left-right direction, the magnet 40 can be accommodated in the magnet accommodating unit 31 on the right side when viewed from the front side of the refrigerator 10, thereby allowing the magnet 40 to be detected well by the magnet detection unit 20.

[0042] In this way, according to the refrigerator 10 of this embodiment, regardless of whether the rotation method of the refrigerator compartment door 12D is "left-opening" or "right-opening", a configuration can be realized in which the magnet detection unit 20 can effectively detect the magnet 40, in other words, a configuration in which the open / closed state of the vegetable compartment door 13D can be effectively detected.

[0043] In addition, according to refrigerator 10, by storing magnet 40 in either one of two magnet accommodating sections 31 depending on whether refrigerator compartment door 12D is a "left-opening" type or a "right-opening" type, the number of magnets 40 used can be reduced compared to a configuration in which magnets 40 are stored in both of two magnet accommodating sections 31, thereby enabling parts costs to be suppressed.

[0044] Moreover, according to refrigerator 10, a plurality of extension portions 32 are provided, in this case, between two magnet accommodating portions 31. With this configuration, it is possible to realize a configuration in which the space between two magnet accommodating portions 31 is filled with extension portions 32, and it is possible to make magnet accommodating portion 31 oriented toward magnet detection unit 20 less noticeable.

[0045] Furthermore, according to refrigerator 10, extension parts 32 are also provided on the outer sides of two magnet accommodating parts 31. With this configuration, it is possible to realize a configuration in which magnet accommodating part 31 is embedded in the middle part of extension part 32 extending in the left-right direction at the rear side of handle part 30, and it is possible to make magnet accommodating part 31 directed toward magnet detection unit 20 even less noticeable.

[0046] Moreover, in refrigerator 10, magnet accommodating section 31 includes slit 34 that communicates between the inside and outside of magnet accommodating section 31. With this configuration, it is possible to easily check from the outside through slit 34 whether magnet 40 is accommodated in magnet accommodating section 31. Moreover, slit 34 is provided on the rear end surface of magnet accommodating section 31. With this configuration, slit 34 can be made difficult to see from the front side of refrigerator 10, and it is possible to avoid impairing the appearance.

[0047] Furthermore, based on which of the two magnet accommodating sections 31 provided in the vegetable compartment door 13D the magnet 40 is accommodated in, it can be easily confirmed whether the vegetable compartment door 13D is the vegetable compartment door 13D corresponding to a case in which the refrigerator compartment door 12D is a "left-opening type" or whether the vegetable compartment door 13D is the vegetable compartment door 13D corresponding to a case in which the refrigerator compartment door 12D is a "right-opening type".

[0048] In particular, in this embodiment, the vegetable compartment door 13D corresponding to the refrigerator compartment door 12D being a "left-opening type" and the vegetable compartment door 13D corresponding to the refrigerator compartment door 12D being a "right-opening type" have the same appearance as seen from the front side. Therefore, the vegetable compartment door 13D corresponding to the refrigerator compartment door 12D being a "left-opening type" and the vegetable compartment door 13D corresponding to the refrigerator compartment door 12D being a "right-opening type" can be distinguished based on which of the two magnet housing parts 31 provided in the vegetable compartment door 13D the magnet 40 is housed in, making it easier to avoid the vegetable compartment door 13D that does not fit the rotation method of the refrigerator compartment door 12D being erroneously assembled.

[0049] Furthermore, according to this embodiment, a common mold can be used as the mold for molding the handle portion 30, whether the refrigerator compartment door 12D is a "left-opening type" or a "right-opening type". In this embodiment, the portion where the wall portion 42 is formed is reversed between the "left-opening type" refrigerator compartment door 12D and the "right-opening type" refrigerator compartment door 12D. Therefore, the left-right arrangement positions of the mold parts for forming the wall portion 42 need to be appropriately changed.

[0050] Furthermore, according to this embodiment, the magnet storage section 31 is configured to protrude upward from the upper surface of the extension section 32. With this configuration, in a closed state where the vegetable compartment door 13D closes the opening 13a of the vegetable compartment 13, the magnet 40 stored in the magnet storage section 31 can be brought even closer to the magnet detection section 20, particularly in the vertical direction. This makes it possible to further improve the detection accuracy of the magnet 40 by the magnet detection section 20, and therefore to further improve the detection accuracy of the open / closed state of the vegetable compartment door 13D.

[0051] The upper surface of magnet accommodating portion 31 may be configured to be completely flush with the upper surface of extension portion 32, rather than protruding from the upper surface of extension portion 32, or may be configured to be slightly offset, for example, by several mm, above or below the upper surface of magnet accommodating portion 31. With this configuration, magnet accommodating portion 31 can be made even less noticeable.

[0052] In addition, this embodiment is not limited to the above-mentioned embodiment, and various modifications and extensions can be made within the scope of the gist of the present invention. For example, the number of magnet storage parts 31 provided in one storage door is not limited to two, and may be one, or may be three or more. In addition, the communication part is not limited to the slit 34, and may be, for example, a hole or a groove, as long as it can communicate between the inside and the outside of the magnet storage part 31. In addition, the storage door on which the magnet storage part 31 and the extension part 32 are provided is not limited to the vegetable door 13D, and may be another storage door. In addition, the refrigerator door 12D may be a so-called French type or double door type door, which is configured to open and close the opening 12a of one refrigerator compartment 12 by two refrigerator doors.

[0053] Although the embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. This new embodiment can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. This embodiment and its modifications are included in the scope and gist of the invention, and are included in the scope of the invention and its equivalents described in the claims.
